I am not at all familiar with this game so may not be able to provide the kind of help that you need, but reading over the walkthrough, it says this about the game:

Quote:

If you have already exhausted all possible clues in a certain area - go to another part of the globe and then come back. New clues might surface - like the appearance of the letters here.

So, it sounds to me like if those things are not showing up for you, then it means you need to accomplish other things first in a different part of the globe, and then these items will show up for you when it's time for them to be there.

thanks that is what i did ,now i have the DVR-GRPS I need to put in the devil's triangle memory card,how do i know the right card to put in ? also where is the play button ? sorry for all the questions.

Maybe someone else will be able to help you here. The problem is that both walkthroughs I looked at don't answer either of your questions, so unless I was sitting here playing the game myself, at that exact same spot, there is no way that I could know, unfortunately. Sorry about that.

Did you click on each link/hint individually as they came up? Because there is a lot of information to be found on that page. If you did, and it still doesn't help, then I really don't know what to suggest other than to read over a walkthrough closely, because there is no way for me to know what you have and have not done up until this point. And looking over the walkthrough, this game definitely seems more complicated than some of the other walkthroughs I have looked at.

And the less linear the game, the harder it is to figure out what someone might have missed.

you got that right. anyway made it to devil's triangle2 and then to chichen itza .saved there .don't ask me how i did it. again thanks for your help..not a easy game at all. also playing Art of murder: FBI Confidential so that my break time.
